Note that while the documentation for Text specifies that its bytestream should be UTF-8, the encoding is not enforced by operations that work with byte arrays.
For example, you can create 256 evenly-sliced splits via the following code sample even though the given byte sequences are not valid UTF-8.
TableOperations tableOps = connector.tableOperations(); TreeSet<Text> splits = new TreeSet<Text>(); for (int i = 0; i < 256; i++) { byte[] bytes = {(byte) i}; splits.add(new Text(bytes)); } tableOps.addSplits(TABLE_NAME, splits);
